Need help! Do jewelers use different UV lights on diamonds

[goffgirl]

I need some help. On my fancy yellow diamond, the GIA report states that the diamond has no fluorescence. However, when I put the stone under a UV light, there was a blue fluorescence.
I'm going to take the ring to the jewelers, who states that their UV light is different than the one I used (it was where I was getting my nails done).
Are there different UV lights used to grade diamonds?
